Detecting Wormhole Attacks in Multi-path Ad Hoc Networks
Peng Cao · Microcomputer Information · 2009
The emergence of multi-path techniques in Ad Hoc network is a new choice because multi-path routing provides means to combat the effect of narrow bandwidth and unreliable wireless links. But the multi-path network under wormhole attack will drop information. More seriously, it will cause network collapse. This paper proposes a new scheme by statistically analyzing the information collected by packets of multi-path network and compared with samples to detect wormhole attacks and identify attackers ’ location. This scheme make Ad Hoc network keep away from the harm caused by wormhole attacks. Simulation results demonstrate that it successfully detects wormhole attacks and locates the malicious nodes in Ad Hoc network .
